Implement a vertical arrangement of rectangular boxes representing workflow steps, interconnected by arrows to illustrate the flow. Include an 'Add App' button at the bottom of each box for seamless app integration. Ensure clarity by numbering each step sequentially. Envision a clear 'Start' button at the top, signaling the initiation of the workflow creation process.
